Abstract: When a multi-channel signal, such as from a 22.2 channel, is rendered to a 5.1 channel, three-dimensional audio signals can be reproduced by use of a two-dimensional output channel. However, when the elevation of the input channel differs from the standard elevation and an elevation rendering parameter corresponding to the standard elevation is used, audio image distortion occurs. The present invention resolves the described issue in the existing technology, and a method of rendering audio signals, according to an embodiment of the present invention, which reduces the audio image distortion even when the elevation of the input channel differs from the standard elevation, comprises the steps of: receiving a multi-channel signal comprising a plurality of input channels to be converted into a plurality of output channels; obtaining elevation rendering parameters for a height input channel having a standard elevation angle so that each output channel provides an audio image having a sense of elevation; and updating the elevation rendering parameters for a height input channel having a set elevation angle other than the standard elevation angle.

Abstract: An audio apparatus and a method of converting an audio signal are provided. The method includes: receiving a first audio signal including a plurality of channels; comparing audio signals of the plurality of channels to estimate a source position of the first audio signal; localizing a source of the first audio signal toward a three-dimensional (3D) position having an elevation component based on the estimated source position; converting the first audio signal into a second audio signal including the plurality of channels and at least one channel having, based on the localized source, a different elevation from the plurality of channels; and outputting the second audio signal.

Abstract: Disclosed are an audio apparatus and an audio providing method thereof. The audio providing method includes receiving an audio signal including a plurality of channels, applying an audio signal having a channel, from among the plurality of channels, giving a sense of elevation to a filter to generate a plurality of virtual audio signals to be respectively output to a plurality of speakers, applying a combination gain value and a delay value to the plurality of virtual audio signals so that the plurality of virtual audio signals respectively output through the plurality of speakers form a sound field having a plane wave, and respectively outputting the plurality of virtual audio signals, to which the combination gain value and the delay value are applied, through the plurality of speakers. The filter processes the audio signal to have a sense of elevation.
